Overview

Open Educational Resources (OER) are educational materials that are freely accessible and openly licensed.  The aim of OERs is to allow users to adapt, share, or use materials with limited or no restrictions. The primary characteristics of OERs are:

  • Free - Resources can be easily found, downloaded, and used without the need to pay for digital access.
  • Open - Materials are licensed under a version of a Creative Commons License (in terms of copyright), or Public Domain, which allows for adapting, sharing, and using said material without infringing copyright.

The 5 Rs (Retain, Reuse, Revise, Remix, Redistribute) is a common metric used to determine if material is "open":

  • Retain - Keep access to the materials after the learning event.
  • Reuse - Use the content in its unaltered form.
  • Revise - Adapt, adjust, modify, improve, or alter the content.
  • Remix - Combine the original or revised content with other OER to create something new.
  • Redistribute - Share copies of the original content, revisions or remixes with others.

These five considerations are important to evaluate whether material is OER or not.  Not everything discoverable on the internet is free to use, open, or can be adapted.

Examples of Search Engines for OER

OASIS - Search engine that allows users to search several OER repositories at once and has filters to search for materials based on type.

OER Commons - OER search engine with deep coverage.

Mason OER Metafinder - Metafinder / search engine developed by George Mason University and devoted to OER.

Creative Commons Search - Search engine for images, videos, and other multimedia that has been tagged as having a Creative Commons License.

Most common search engines (e.g. Google, Bing) have an advanced search feature to filter results based on copyright or usage rights.

Examples of OER Textbooks

OER textbooks exist for a variety of disciplines, and dedicated collections are hosted and searchable online.

BC Campus OpenEd - British Columbia's repository of quality OER Textbooks is frequently updated and contains texts for a variety of disciplines.

Open Textbook Library - Resource collection for OER Textbooks based out of the University of Minnesota.

OpenStax - OpenStax is a nonprofit educational initiative based at Rice University, with a collection of core OER Textbooks and other instructional resources (lecture slides, test banks, etc.).

Galileo Open Learning Materials - As part of the Affordable Learning Georgia initiative, the University System of Georgia has developed OER Textbooks in a variety of subjects.

LibreTexts - Resource collection for finding OER Textbooks in the STEM discipline areas.

Open Oregon - Initiative based in Oregon that includes select OER Textbook titles.

Open SUNY Textbook Library - Open SUNY (State University of New York) focuses on OER courses and also has a collection of OER Textbooks (Milne).

  • OASIS OER Search Engine - This search engine pulls results together from most of the above sources into a single interface.

Examples of OER Repositories

In addition to specific repositories focused on textbooks, there are repositories that can be used to find all types of OER:

OER Commons - One of the larger repositories of OER content; it focuses on a variety of disciplines.

MERLOT - Curated online library of OER that contains contributions from various academic institutions.

Skills Commons - Created by a federal grant, focuses on OER related to workforce training and industry.

Open Course Library - Started by the State of Washington's Community and Technical Colleges Consortium, it includes OER resources and low-cost alternative instructional materials.

The Orange Grove - Florida's Open Educational Resource Repository has texts, materials, and learning objects across various disciplines.

Benefits

OER provides learners with financial and academic benefits in the areas of cost, retention and grades, and pedagogy and open educational practices.

Cost - Based on data from the Bureau of Labor Statistics, textbook prices increased 88% between 2006 and 2016.  However, ongoing efforts to encourage adoption of OER and affordable textbook alternatives are making an impact.  According to research from the Association of American Publishers, average student spending on textbooks and course materials declined 41% between 2012 and 2023. Research from the College Board indicates that the average student budget for textbooks, course materials, and other related supplies in 2023-2024 was $1,470 at a public two-year institution of higher learning, and $1,250 for a public four-year institution of higher learning.

Retention and Grades - There is a positive impact on student retention and course grades. A large-scale study by the University of Georgia found that students in courses that used OER had grades that were 6.9% higher for non-Pell recipients; and 10.98% higher for Pell recipients.  The study also found that fewer students in courses that used OERs received a D, F or Withdrew, when compared to courses that used traditional materials.

Public Interest Research Groups (PIRGs) studied the effects of high textbook costs on student course enrollment.  In a student survey in 2020, 65% of students reported foregoing the purchase of an assigned textbook because of cost, and 90% of students reported being significantly or somewhat concerned by textbook costs.

These studies suggest that a student's academic performance and retention can be positively affected by their ability (at low or no cost) to begin a course with the textbook in hand.

OER Enabled Pedagogy and Open Educational PracticesOER Enabled Pedagogy is a term that describes the set of teaching and learning practices that can only exist when open materials (OER) are utilized. Materials with copyright restrictions restrict the ways in which students can learn from the materials. In essence, using OER materials allows for higher levels of learning, as students can revise/adapt/contribute to the learning materials themselves and demonstrate their mastery/knowledge in the subject.

Creative Commons

OER often utilize Creative Commons Licenses because many of these licenses allow for materials to be reused, redistributed, modified, or altered. Works are generally protected by copyright as soon as they are created, which imposes restrictions on how the material can be used or shared.  Copying and distributing copyright-protected material online is often illegal, although Fair Use and Classroom Use Exemptions provide some leeway for use of material in educational settings.

The elements of a Creative Commons License are:

  • Attribution (BY) - Credit must be given to the original creator.
  • Non-Commercial (NC) - Only noncommercial use of the work is permitted.
  • Share Alike (SA) - Adaptations must be shared under the same terms.
  • No Derivative Works (ND) - No derivatives or adaptations of the work are permitted.

These four elements combine to form the six different types of Creative Commons (CC) Licenses, listed here from most to least permissive:

  • CC0 or CC Zero - This license is a public dedication tool which allows creators to surrender their copyright and place works into the worldwide public domain. CC0 licensed material can be redistributed, remixed, adapted, or built upon in any medium or format, with no conditions.
  • CC BY - This license allows materials to be distributed, remixed, adapted, and built upon in any medium or format, so long as attribution is given to the original creator.  The license allows for commercial use.
  • CC BY-SA - This license allows materials to be distributed, remixed, adapted, and built upon in any medium or format, so long as attribution is given to the original creator.  Reusers must license their modified materials under identical terms.
  • CC BY-NC-SA - This license allows materials to be distributed, remixed, adapted, and built upon in any medium or format for noncommercial purposes only, so long as attribution is given to the original creator.  Reusers must license their modified materials under identical terms.
  • CC BY-ND - This license allows materials to be copied and distributed in any medium or format in unadapted form only, with attribution given to the original creator.
  • CC BY-NC-ND - This license allows materials to be copied and distributed in any medium or format in unadapted form only, for noncommercial purposes only, with attribution given to the original creator.
